Seat Vibration Massage
Computer Body Scan System Equipped with the latest technology, it allows for the rollers to map the back curvature with even more accuracy, which translates into a more precise massage hitting all the key areas. Regardless of your body type, this highly advanced chair will self-adjust making each massage experience feel customized.
2 Stage Zero Gravity Inspired by NASA technology, the Zero gravity position is the perfect position to enjoy a massage, aligning your back relative to your thigh at an optimal level of comfort. When reclined into the zero gravity position, the complete weight of your back is virtually supported by the backrest which maximizes the intensity of the massage. This also reduces the vertical stress on the spine. There are 2 stages of zero gravity, the 2nd being more reclined. Study show that when the legs are at or above heart level, it promotes better circulation.
True Ergonomic S-Track The OS-4000 Zero Gravity massage chair is ergonomically designed to contour a variety of spine shapes. The Spine curvature is unique from one individual to the next. The S-track system allows the roller heads to massage along the back from the neck down to the lower spine with a consistent pressure in the massage, along with a comfortable support. The typical massage tracks, being linear, create an inconsistency in pressure applying weak massages in the neck and lower back.
Next Generation Air Massage Technology The airbag massagers have been upgraded and engineered, reducing the number of airbags and valves but at the same time increasing the surface coverage. Less power is consumed and runs more quietly with the reduction of air pumps and valves, allowing for a more tranquil massage experience. The material used to create the air bags have also been modified with industrial grade material for durability, yet soft and pliable to provide comfort and consistency.
Arm Air Massagers Along with mechanical advancement the material has also incorporated some upgrades, such as the arm massaging area. Using a durable spandex, the bottom portion of the arm massager has been lined with small rubber bumps to invigorate the senses as the air bags compress the tops and bottom of the forearm and hands.
Hips and Lumbar Squeeze Hip airbags are located on the left and right side of the seat base. When inflated it will compress the hips inwards, applying a firm massage to the thighs and hips. When the airbags inflate on the hips it may also be used to hold the user in place as the back massager rollers move downwards, working on the lower section of the back. On the lower portion of the backrest, there are 2 lumbar airbags. When inflated it will squeeze the outer portion of the lower back inwards, providing a mild massage.
Foot and Calf Massage There are multiple air bags along the sides, and back of the legs, and feet which inflate to apply a compression massage. Located along the bottom foot massager are 2 pressure point nodes. When the air bags inflate, the foot and calves are firmly pressed down on the pressure points for an invigorating massage. The experience simulates a massage therapist pressing down with their thumbs.
Lower Back Heat Therapy There are 2 heating pads, one on each side in the lower lumbar area. The heat therapy is a great compliment to roller and airbag massage. The heating pad is not intended to be use for more than 30 minutes a day or the duration of a massage preset program.
Shoulder Airbag Massage The outer and top part of the shoulders have not been forgotten. Airbags have been placed on both sides of the chair. As the airbags inflate the shoulders pressed inwards and back pinning your shoulders the backrest. This will stretch out muscles in the shoulder region where carry most their tension.
